BUNG AND BUSHING THEREFOR.

Specification of Letters Patent.

Application filed June 7, 1912. Serial No. 702,359.

To all whom 'it may concern:

Be it known that I, HENRY NADORFF, citizen of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented new and useful Improvements in Bungs andBushings Therefor, of which the following is a specification.

My present invention pertains to bungs and bushings therefor; and itconsists in the peculiar and advantageous bung and bushing, hereinafterdescribed and claimed, designed more particularly as an improvement uponthe bung and bushing constituting the subject matter of myLetters-Patent Number 652,858, dated July 3, 1900.

In the drawings, accompanying and forming part of this specification:Figure 1 is a diametrical section showing my novel bushing and the bungsecured therein. Fig. 2 is a view illustrative of the inner side of thebung and bushing. Fig. 3 is a side elevation showing the inclined planesof the bushing which serve by cooperation with the lugs of the bung tohold the flange of the latter under pressure against the gasket.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

The bushing of my improved device is flanged at its outer end, asindicated by 1, and is exteriorly threaded at 2 and provided at itsinner edge with oppositely disposed inclined planes 3. One of the saidplanes 3 extends in one direction from a kerf 4: formed in a flange 5 atthe inner end of the bushing, and the other plane 3 extends in theopposite direction from another kerf 4; formed in the flange, the saidflange 5 being disposed inward, and being provided with stops 6 andguards 7 for assuring the movement of the bung lugs, hereinafterreferred to, in the proper direction incidental to the locking of thebung in the bushing. It will also be noticed that the bushing ischaracterized by a gasket seat 8, formed by the before mentioned flange1.

The gasket 8 which may be made of rubber, composition or any othermaterial compatible with the purpose of my invention, may be arranged inthe said seat 8, or may be made to tightly fit the bung so as to be Iremovable with the latter, in the discretion of the manufacturer of mynovel device.

For the sake of cheapness the bung comprised in my improved device iscast of iron or other suitableinexpensive material. The sald bung 1slmperforate, and is constructed for the engagement of the convent1onalor any other suitable key employed in the looking and unlocking of thebung in the bushing. At its outer end the bung is exteriorly flanged, asindicated by 9, and between the saidflange and the seat 8 in the bushingthe gasket 8 is. entirely inclosed and is compressed and held underpressure. At 10 the bung is provided with an intermediate portiondesigned to fully occupy the interior of the bushing, and the saidintermediate portion 10 merges into a reduced portion 11 of a diameterto extend through the inner flange 5 of the bushing. On the said reducedportion 11 and at diametrically opposite points are radial lugs 12,designed and adapted to cooperate with the flange 5 in the locking ofthe bung in the bushing.

In the practical use of my novel device, it will be manifest that inorder to lock the bung in the bushing it is simply necessary to move thebung rectilinearly into the bush ing and so that the lugs 12 of the bungpass through the kerfs of the bushing, after which the bung is turnedabout its axis, whereupon by reason of the lugs 12 moving against theinclined planes of the bushing, the gasket will be compressed betweenthe bung and the bushing, and the bung will be frictionally securedagainst casual displacement, and the closure will be efl'ected in aperfectly air-tight manner.

To remove the bung, the operation described is reversed, that is to say,the bung is turned about its axis in the direction opposite to thatbefore referred to until the bung lugs bring up against the stops on thebushing, and said lugs are in registration or alinement with the kerfsin the bushing, when the bung can be expeditiously and easily withdrawnendwise to afford an opening into the barrel.

In addition to the function hereinbefore ascribed to them the guards 7on the bushing serve to effectually prevent projecting portions of astave from interfering with the proper cooperation of the bung lugs withthe inclined planes of the bushing.

Having described my invention, what I claim and desire to secure byLetters-Patent, is:

The combination with a bushing having an exteriorly threaded portion andalso having an outwardly directed flange, of right Patented Oct 1, 1912.

angle form in cross-section, at the outer end of said port-ion and aninwardly directed flange at the inner end of the portion and also havinga kerf in the second-' provided at its outer end with an outwardlydirected flange and also provided with an intermediate portion of a sueto snugly occupy the portion of the bushing between the first andsecond-named flanges and further provided with a reduced inner portiondesigned to rest snugly in the second-named:

flange and equipped with a radial lug adapted to pass through the kerfin the inner flange and cooperate with the inclined plane thereof, and agasket surrounding the bung and interposed between the flange thereofand the right angle flange of the bushing and adapted to be entirelyinclosed by said flanges.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

HENRY N ADORFF.
